News: Scientists at the Department of Biotechnology (DBT) have reported for the first time a reference-grade whole genome sequence of a highly salt-tolerant and salt-secreting true-mangrove species Avicennia Marina. Read News Here.

Avicennia marina.

  1. Avicennia marina is one of the most important mangroves species found in India.
  2. It is a salt-secreting and salt-tolerant mangrove species that grows well in 75% seawater and can handle >250% salt in seawater.
  3. It is among the rare plant species, which can excrete 40% of the salt through their salt glands, moreover italso has a unique capacity to exclude salt entry to the roots.



  1. A mangrove is a shrub or small tree that grows in coastal border areas in saline or brackish water.
  2. They occur worldwide in the tropics and subtropics, mainly between 30° N and 30° S latitudes, with the greatest density within 5° of the equator.
  3. They are salt-tolerant trees, also called halophytes, and can live in harsh coastal environment.
  4. Mangroves contain an arrear-like complex salt filtration and root system to manage with salt water immersion and tidal force.
  5. They can sustain themselves in low-oxygen levels usually found in waterclogged muddy regions.
  6. They are a unique group of species found in marshy regions where tides and estuaries meet and survive a high degree of salinity by adapting to changing environment
  7. They provide habitat for a diverse amount of species, protect shores and also form a link betwenn both marine and terrestrial ecosystems.
